Merge colors.css into wp-admin.css. Non-default color schemes became overloads rather than swaps in the 3.8 redesign. Benefits include:

* No more border-width, border-style, border-color insanity.
* Point releases are much less likely to require extra finagling to avoid rebuilding the color schemes.
* Yours truly has a better overall vision of ~14,000 lines of admin CSS and where we go from here.

1,065 net lines of red, y'all.

Some tweaks to [27106]:

* Add more @todo markings and remove one that's been resolved.
* Restore a missing comma in a `.wp-badge` background rule, and add a comment reminding us why it's there.

In `get_terms()`, don't set automatically `hierarchical` to `false` when `parent => 0` is passed. The default value for `parent` is `''`.

In `_get_term_children()`, don't skip a top-level term without first including its children in the returned term list. Ironically, the call to `_get_term_children()` in `get_terms()` has a comment stating `"Make sure we show empty categories that have children."`, but it didn't work if you were retrieving top-level categories only.

All unit tests pass. Added a unit test based on the use case described in this ticket.

Fixes #26903.
